There are two visible issues:

1) Any kind of shutdown attempt does not shut the active connections down
2) While they're connected nobody else (including SYSDBA) can connect even if the multi-user shutdown was requested

Everything works as expected with zero timeout interval (-force 0).

Additional comments:

In summary, shutdown -force does not shut down existing connections. It does put the database into a shutdown mode. However, in multi mode, privileged users cannot log in until the "trapped" user sessions are terminated.

(There's another bug apparent here, I think, in that a user created with global admin privileges - WOMBAT - can't put the database online.)

Confirmation by Helen:

I confirm similar (although not exactly the same) behaviour w. v.2.0.7 and 2.1.5. Don't have a v.1.5 Windows box available.

The difference: with 2.0.7 and 2.1.5 the message to client when connection is refused is "Statement failed, SQLCODE -903 database {file-path} shutdown

With 2.5.1 it is nasty "Statement failed, SQLSTATE = 08006
connection lost to database" with no useful information.
